SM U-90 was a Type U 87 u-boat of the Imperial German Navy during World War I.^[1]

The commander, Walter Remy, was noted for making regular stops at the very remote UK island of North Rona for provisions, including fresh mutton.

On 31 May 1918, U-90 torpedoed and sank USS President Lincoln. The ship was a former Hamburg America Line steamer of the same name seized by the United States and employed as a troop transport. From the U.S. Navy crew that abandoned the sinking vessel, U-90 captured Lieutenant Edouard Izac, eventually taking him to Germany.
